You can also gain several feet at any of the smaller inlets if you time your approach with the high tide.
Timing your approach/passage for HIGH tide isnt necessarily wise when 'shooting inlets'. At inlets the historical CURRENT is the most important factor and the max current is totally dependent on how the specific inlet historically 'flows' .... as in many the max. current flow is 'just before' HIGH tide and WAY before LOW tide ... and every (small) inlet has its own individual current flow characteristics vs. the state of the tidal heights.
You really need the CURRENT FLOW data to safely 'shoot' an unfamiliar inlet, especially in adverse conditions. - Eldridge tables, PC current prediction programs, etc.
